I was only an RA/TA, so I can't say what it's like for female faculty. There were actually plenty of RAs and TAs in the mechanical engineering department when I was there, and in general the culture from the top down was positive and encouraging. Beware the undergraduates, of course; they can be real chauvinists.

It's a pretty standard university engineering department (read: super male), but there are some really excellent female role models here, too.
